Notes. Metallicity is represented by [Z], with a value of 0.55 for WASP-80b (Batalha & Marley 2020). The listed Tint values correspond to those used in the initialisation of the GCM model. Optical constants are taken from: Na2S – Montaner et al. (1979); Khachai et al. (2009), KCl – Querry (1985), MgSiO3 – Scott & Duley (1996).
